The term McMansion is likely to stick around (even if is used poorly at times) but more interest may be shifting to the giga-mansion.  A Motley Fools podcast provides some information:

First we had mansions. Then we had mega-mansions. And McMansions. Now we have giga-mansions. Yes, it’s a growing trend of massive houses usually built in the LA area on spec. They are massive, expensive, and outrageously ostentatious. Let’s see if you two can answer some trivia around some of the most expensive pieces of residential real estate on the market…

The One will be America’s largest house on the market at 100,000 square feet. It will be the most expensive private residence when it comes to market. It boasts four swimming pools, a nightclub, a room where the walls and ceiling are filled with jellyfish. It will have a 30-car gallery. Because of this price you don’t call it a garage. Of the 20 bedrooms, how many are in a separate building just for your staff?…

Let’s move on and talk about the house called Billionaire. It’s 38,000 square feet. It was America’s most-expensive house on the market when it was listed for $250 million in 2017. The property is in the exclusive Los Angeles suburb of Bel Air. It has 12 bedrooms, 21 bathrooms, three kitchens, a 40-feet James Bond-themed cinema, six bars, two fully stocked champagne cellars, and the helicopter from what 1980s television series? Rick knows this. He can’t wait to say it…

Southwick: A $1 billion lot. Now we’re going to go to The Manor. The largest home in LA was actually built in 1988 by the TV show producer Aaron Spelling and his wife Candy. The 56,000 square foot, 14-bedroom, 27-bath home originally was built for $12 million. They sold it all in a cash deal for $85 million in 2011 to the 23-year-old daughter of someone wealthy. Don’t worry about it. She renovated much of the house, since it had some very quirky spaces, including a flower-cutting room, a humidity-controlled silver storage room, a barber shop, and three rooms for doing what common birthday and Christmas activity?

One of the major critiques of McMansions involves their symbolic nature: they are associated with sprawl, wealth, and conspicuous consumption. All of these appear to be in play with the examples from the Los Angeles area cited above: a region known for cars and highways, entertainment celebrities and executives along with other wealthy people, and a constant need to stand out from the rest of the area.

But, McMansions have key differences from this supersized homes. They are generally smaller – roughly 3,000-10,000 square feet – and more often found in “typical” neighborhoods. They are often mass-produced. They are often criticized for their architecture while megahomes take more flak for their size. Perhaps most importantly, McMansions are within the reach of more Americans. Depending on the housing market, an upper-middle class household can acquire a McMansion but these giga-mansions are only for the wealthiest.

If the ultimate concern behind critiques of McMansions is their unnecessary size and flaunting of wealth, then the spread of giga-mansion might relieve some of the pressure. Granted, there will always be more McMansions but it is easy to focus on these outsized homes and their owners. Why criticize the top 10-20% of American homeowners for their McMansion choices when the giga-mansions of tomorrow constructed and owned by the top 0.1% of homeowners are so ridiculous and unnecessary?
